Several factors indicate that the mechanism needed to regulate insurance at the federal level could be smaller than that of the combined states. About half of state insurance bureaucrats work to review insurance company rate filings; the proposed federal agency would not do that. On the other hand, the legislation before the House (although not Geithner’s proposal) would require the establishment of federal insurance regulation offices in all 50 states. This may be unnecessary and could limit flexibility. Sparsely populated states - Wyoming, for example - probably do not need their own offices, while largely populated states like Florida, where insurance is a major political issue, may find it better to have multiple offices. It is probably best to let the Treasury Department or some other federal agency decide on the specific locations of offices rather than having Congress mandate it.
